[PATCH] Added array support to hgweb

[Jeff Sipek]

The following patch adds array support to hgweb templates.

For instance, one can pass the template class a dictionary (it works
with tuples and lists as well) containing elements:

test = {1: 'foo', 'a': 'bar'}

and then, anywhere in the template, he can access either location by
writing:

#test[1]# or #test['a']#

of course you can still use all the filters you are used to:

#test['a']|age# works just as expected.
